Application filed May 23, 1919. Serial No. 299,116.

To @ZZ wiz/0m it 'may concern lie it known that l, JOHN l). lllan'rnn, a"

citizen of the Unit-ed States, residing at tllentown, in the county ot Lehigh and State of Pennsylvania, have invented new and useful lmprovementsin Shovels, of which the followingr is a specification.

This invention relates to shovels, the objiect being to provide a shovel which is com? bined with aconveyor or loading mechanism For use in mines.

The principal object ot the invention is to Another object is to provide a machine` which may be turned horizontally at various angles to permit of a change of position ot the shovel without moving the machine proper.

i Afurther object of the invention is to provide a machine which `in addition to including all of the above and many other advantages` will materially reduce the cost ot production, the use of the machine being possible in places whose small :ireakprohibits the use ot machines of the usual character,

Various other objects and advantages ot the invention will appear as the following description is read in connection with the accompanying drawings. l l l In the drawings: t

Figure l is a side elevation ot a shovel embodying the present invention. y i

Figure 2 is a top plan view of the same.

.Figure is an enlarged view ot the torward end ot the shovel, the parts being at the limitolf their 'l'orwardmovement Figure 4L shows the position .ot the parts in the act of unloading the shovel into the transfer pan, the parts being in theirinitial unloading position. y i n l Figure 5 shows the shovel at theinish of its unloading position. v Figure 6 is a view similar toFigure` 5, with the parts in position occupied just prior to the unloading` of the transiter pan.

Figure 7 is' an "enlarged detail. sectional view of the 'forward end olithe machine,

with the parts in the position' assumed just after the unloading of the shovel into the transfer' pan.

Figure 8 is a view similar to Figure T showing the position oit' the parts the transfer paniis unloading upon the con veyor.

Figure 9 is a skeleton view illustrating` the trame ot the machine, the pivotedboom and associated parts, certain parts being omitted, i Reterringto the drawings in det-ail, wherein like characters of reference denote corre-v sponding parts, the numeral l() .indicates a truclnwhich is mounted upon traction wheels il, suitably journaled upon the truck and which are designedto operate over alvtraclr l2.

Mounted upon the truck is a turn-table 13, the latter being rotated upona vertically disposed siaft 14, and supported; upon wheels or rollers l5, travelling over the truck platform.

The truckl() carries a suitable supporting` 'trame 16, upon whichris mounted a motor 1T, electrically or otherwise operated from a suitable source of @power (not shown). Also mounted above the truclr l() upon antitriction bearings 1S are arms 19, thelatter t having pivotallymounted at their outer ends upon a shaft 20, a boom. This boom is formed of a pair of arms 2l, arranged upon each side ot the arms 19, the tormer having rigidly secured thereto spacedy upper and lower guide rods22 and23, the latter being also spaced` outwardly trom the arms 2l. The inner ends oi each o'" the arms'2il arc connected to a toothedseginent 24 through the medium ot a link 25, the segment being mounted tor pivotal movement, as shown at 26. vertically disposed shaft 27 has secured y y by a hand wheel 29. I it will be'apparent that by rotating the worm 28, the segment 2e will be moved upon the pivot 26 and through the link connection 25, the arms 2l ot the boom will be swung upon the shaft 2Q, so that the outer ends ot thesaid arms may be raised or lowered, as desired.

Mounted `for sliding `movement upon the thereon a worm 28., which is operated y guide rod 22, is a cross headBO, one end ot which has pivotally mounted thereon, as'

shown at f-Bl, shovel or dipper 32. "The opposite end ot the crosshead i ally mounted thereon, as shown at 33,a pan 34, the pan and clipper beingconnectedv so `as to previdetor simultaneous pivotal move-'Q 30 has pivotf vsegmentel genre 35 rook the has been inovecl lol a` loweref1 yposition through 4he action o' i 30,.v The yclog 50v ie fasi;-
